Abstract
A CMOS wideband transimpedance amplifier with multiple-resistive feedback loops is reported for first time. This amplifier was fabricated by the 0.35-μm CMOS process. Multiple-feedback technique was used to achieve terminal impedance matching and wide bandwidth. The experimental results showed that a transimpedance gain of 51.7 dBΩ and a 3-dB bandwidth of 2.1 GHz were obtained. High input P1dB of - 5 dBm and input IP3 of 1 dBm were also measured. The high dynamic range and high linearity achieved were attributed to the multiple feedback technique used.
